Welcome. As many would say, "down the slippery slope"........
Yes your rifle would be more suited for a factory class type of match/competition be it group or score. There is nothing in stopping you from shooting or trying out a group BR match. In regards to score matches I am not sure what is held in Alberta. There are some clubs that have local fun shoots that you could try. First that comes to mind is Lethbridge. I believe they have some. Group well when you hear from Rick there is Rosebud.
Optics for the type of shooting we usually talk about on this board, 36X, 40X, or 45X fixed scopes.
36X there is Sightron, Weaver, Leupold
40X Sightron, Leupold, March
45X Leupold, Weaver(somwhere in this range), March
45 and higher March
Buy what you can afford. You like Leupold? I like Leupold. Have them on my BR rifles, both my .223's, and one that was built for BRSC that I won.
I would stay away from the variables unless you really need it. Then I would go March. The price tag is more but if it is a NON issue, buy what you can AFFORD.
Good Luck and maybe see you in Calgary this year.
